Title:
IMAGING DEVICE FOCAL PLANE SHUTTER AND IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2017058469
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To attain prevention of exposure unevenness or increase in durability in an imaging device focal plane shutter adopting a blade inclination adjustment mechanism and an imaging device.SOLUTION: An imaging device focal plane shutter comprises a shutter blade 20 including blades 23, 24, and 25 connected to freely rotatable two arms 21 and 22 with respect to a base plate 10. An inclination of the shutter blade is adjusted by two-dimensionally moving a rotating fulcrum of one arm 22 of the two arms, and thereby even when the arms 21 and 22 constitute a non-parallel link, a connecting hole of a connecting shaft connecting the arm to the blade is formed so as to be maximum on a rotating fulcrum side, which in turn the shutter blade can smoothly work.SELECTED DRAWING: Figure 9
